Pyrazolenine ring

Pyrazole from pyrazolenine ring van Alphen rearrangement... [Pg.398]

Irradiation (s. a. under lithium compound) Gyclopropene from pyrazolenine ring... [Pg.471]

Sparse data on the pyrazole isomers, pyrazolenines and isopyrazoles, are presented in Table 12. Besides the obvious upheld effect on the chemical shift due to the suppression of the ring current, these compounds behave normally. Data on pyrazolidinones and their salts show the behaviour of cyclic hydrazides (66T2461,67BSF3502). [Pg.185]
